Hello Dear,

This equation is clearly based upon energy conservation . This equation in physics giving the kinetic energy of a photo-electron emitted from a metal as a result of the absorption of a radiation quantum: E _k = h ν−ω where E _k is the kinetic energy of the photo-electron, h is the Planck constant, ν is the frequency associated with the radiation quantum, and ω the work function of the metal It is clearly based upon energy conservation. Einstein theorized that the energy in each quantum of light was equal to the frequency of light multiplied by a constant, later called Planck's constant. A photon above a threshold frequency has the required energy to eject a single electron, creating the observed effect.

Good Luck

Hii Aspirant,

Einstein's photoelectric equation is based on the law of condervation of energy.Einstein resolved this problem using Plank's revolutionary idea that light was a particle.The energy carried by the each particle of light (photon) is dependent on the light's frequency.

Hope it helps!!

Hello,

Einstein photoelectric equation is based on law of conversation of energy. the law of conservation of energy states that the total energy of an isolated system. You can go through the link to know about the Einsteins equation.
